Those pleased with the success of their efforts to shave off the weight in January might want to look away now.

Because all of their hard work could be undone by this 1ft tall burger, should they take on the challenge to eat it in just 20 minutes.

But those who tackle it can shrug off some of the guilt - because the gigantic test is all for the sake of raising money for a cancer charity.

Mounds of meat This is the monster burger challenge that gives you just 20 minutes to try and defeat the massive 2.25lbs burger

Measuring in at a foot tall and loaded with six burgers, six slices of bacon, six onion rings, cheese and salad, this is not one for the faint-hearted

The competitor will have just twenty minutes to plough through six 6oz beef burgers, topped with six rashers of bacon, six deep fried battered onion rings, six slices of cheese and six rings of fresh onion.
